Worm Gear Motors from Ruhrgetriebe
The advantages of worm gearboxes
Our worm gear units feature closed and robust housings that provide maximum stability when mounted and are suitable for both directions of rotation.
The steel worms are hardened and ground, while the worm wheels are made of high-quality special bronze with excellent sliding properties. By using synthetic gear grease or oil (with NSF H1 approval), you benefit from low noise emission and a long gearbox lifespan. Each gearbox is equipped with ball bearings, ensuring above-average longevity even in continuous operation and various installation positions.
Based on our many years of experience, we have preconfigured the most common modular systems for you. This provides you with a technically and economically mature solution in every respect for the majority of applications.
Flexibility and speed in worm gear drive solutions.
Depending on the application, our worm gearboxes can be supplied in various configurations with AC, DC, or synchronous motors. Our worm gearboxes are available immediately from stock, or we assemble them from in-stock components with short delivery times. We support you in selecting the right worm gearbox drive solutions for your needs. Talk to us - we love challenges.
